MECHANICAL TOY.

Application filed February 6, 1925. Serial No. 7,247. i

To all whom it may concern:

Be it known that I, LESTER S. GUNDnR- MAN, a citizen of the United States, residing at 251 Kennedy Ave, North Side Station, Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Mechanical Toys, of which the following is a specification.

This invention relates to a class of toys in which a car or the like gravitates along an upper track and a lower track in a novel and interesting manner.

The object of the invention is to provide a mechanical toy in which a car may be raised to an upper track along which it rolls until it strikes the end of the track then it turns over completely and alights on a lower track and gravitates to the'opposite end, to again be elevated.

' In the accompanying drawings, Fig. 1 is a top plan of the toy with the car removed.

Fig. 2 is a side view of the assembled toy showing the parts in one position;

Fig. 3 is a section of the toy on line Y-Y of Fig. 1, the parts being in a different position.

Fig. i is an end view of the toy showing the reversing end of the tracks.

Fig. 5 is an enlarged sectional view of the overturning end of the upper track.

Fig. 6 is an enlarged plan of the joint. on the stationary part of the upper track.

Fig. 7 is a cross section of the track as shown in Fig. 6.

Fig. 8 is an enlarged side view of' the joint on the removable section of the upper track.

Fig. 9 is a top plan view of a preferred form of rolling object.

' In carrying out my invention, I employ a track 10 which includes a removable sec tion '11, the entire lower track comprises two sections a stationary track 12 and an elevating section 13, these tracks being formed from several strips of sheet metal of suitable sizes and are supported by a base 14 with uprights 15 and 16 upon which the tracks are mounted, the upper track slopes in one direction and the lower track slopes in a reverse direction. At one end of the track 10 it extends downward abruptly and 5, their outside edges being supported by the flanged portions 18 of support 16, at the opposite end of track 10 is a pair of parallel slots 19 as shown in detail section Fig. 6.

In Fig. 8 is shown an enlarged one end of the loose track 12 having a pair of parallel formed lugs 20bent downward and arranged to pass through the slots19 and engage with the underside of the track section of 10 for the support thereof, as shown in Fig.

2 and Fig.3, the loose track 11 may be raised slightly by the elevating track 13, this man ner of connection will keep the track in a true alinement and facilitate in the easy removal thereof. 2

"The one end 21 of the lower track 12 is turned upward more than the general downward slope of the trackpin order that the object, hereinafter described, may be caught and given added momentum. The raised side sections 22 of the track 12 is for guiding the object when alighting on the track. One endof the elevating track 13 is pivotally mounted at 23 to the upright 15.

connecting bar 24 is pivotally mounted at 25 to the elevating track 13 the opposite end of the connecting bar being pivoted at 26 to the driving motor wheel. The driving motor 27 may be of any conventional type.

A spring 28 is mounted over the pivot stud 23, one end of the spring resting against the track 13, to assist the motor in raising the object to the upper track, the spring being of such tension that the power of the motor is utilized to lower the end of the' track, which equalizes the running of the motor and the power required to operate the toy.

The outer end of the track 13 is provided with an abutting plate 29 for stop ping the travel of the rolling object.v A pair of parallel openings 30 are provided in the track 13 for retaining the rolling object in posit-ion until the said object is elevated to the proper position. The tracks are formed into a channel section as shown in Fig. .7 the flanged sides being for guiding the rolling objects along the tracks. The rolling object is shown in Fig. 9, preferably as a miniature car 31 having flange sections 32 which project out in between thewheels and extend outward to the outside edge of the wheels. This fiange section 32 strikes car to turn over completely and alight on the lower track 12. The upright 16 .is provided with an opening 33 through which the track 12 extends and for the car to pass.

From the foregoing description, when in ec ne ion wi h the ac ompanying drawing, the advantages of the construction and method of operating will be readily apparent to those skilled in the art to which the invention appertains, and while describing the principle of operation of the invention together with the device which is now considered to be the bestembodiment thereof, it is tobe understood that the device shown is merely illustrative and that various changes in the form. proportion and the m no det '0 the c n truction may b resorted to without departing from the principle or scope of-the claim I cla m as my nvention. 7 1. A toy compris ng upper track,

lower track of greater length than upper track, means for elevating the end of one section of the lower track and to elevate object to travel on the track by gravity, the elevating of one end of the lower track serves to elevate the object from the lower traclr to the upper track from whence it rolls in one direction and then reverses and rolls in an opposite direction to return to position to be again elevated.

52. A toy comprising an upper track one section of said track being stationary and one section being loosely hinged at one end thereto for contacting with the elevating track, a lower track and means for positively elevating the endof one section to elevate an object adapted to travel on the said upper track in one direction, when leaving said track said object being turned over and travels in an opposite direction on the lower track to its initial position.

3. A toy comprising an upper track, a lower track one section of said track being stationary, the other section of said track being pivotally supported at the inner end the outer end being in position to positively raise an object to the upper track, the outer end of said track carrying a. pair of parallel slots means of retaining an object in a position until elevated, whence the object rolls by gravity and will return-to its initial pe t A ev m risin a u p r lower track of greater length than the upper track which is unequally spaced above the lower track, one end of the lower track section being arranged to move upward tocontact with the upper track,
